If you can recall some of the most famous songs from the early '70s, 'Roop Tera Mastana' must surely be on the top of your list.

This iconic song from the popular movie Aradhana (1969) is a must have in the playlist of not just the previous generation, but today's too.

Gaurav Kotian's rendition of the song on a glass harp — comprising a number of wine glasses filled with varying levels of water — stands out not for its uniqueness, but also the otherworldly sound the 'instrument' produces.

Kotian has also done similar covers of songs such as Celine Dion's 'My Heart Will Go On' and 'Jeena Jeena' (from the 2015 film Badlapur), which you can check out here.
